Document Type and Number:
WIPO Patent Application WO/2018/083964
Kind Code:
A1
Abstract:
The present invention facilitates the adjustment of the axial clearance between a stationary scroll and an orbiting scroll. This scroll compressor is provided with: a stationary scroll 320 and an orbiting scroll, which are engaged with each other; a front housing 220 for containing the stationary scroll 320 and the orbiting scroll; and a rear housing 240 joined to the open end of the front housing 220. The stationary scroll 320 has: a bottom plate 322 fitted to the front housing 220; and a flange 326 gripped between the joining surfaces of the front housing 220 and the rear housing 240. The front housing 220 and/or the flange 326 of the stationary scroll 320 has formed therein a recess 220E or 326A which permits the stationary scroll 320 to be axially displaced toward the orbiting scroll by differential pressure acting on both surfaces of the bottom plate 322 of the stationary scroll 320.
